In many ways a TAA makes accessing the information much easier. In a round dial airplane (RDA), in order to determine his current position, the pilot has to tune in two VORs, center the needles on two OBSs, then pull out the sectional and mentally or physically plot the approximate location of the airplane, which has already moved since the needles were centered. Or, if the airplane has DME, the pilot can go through a similar process using one VOR along with the distance from that VOR. In a TAA, the pilot simply looks at the little airplane on the screen and immediately knows his exact location, along with the location of all controlled and restricted airspace, airports, cities, roads and weather. It doesn't get much simpler than that!
